IMPROVEMNT IN .AXLE-GAUG-E.

The Schedule referred to in these Letters Patent and making part of the same To Il whom it may concern.'

Be it known that I, ROLLIN C. KELLY, of Brandon, county of Fond duV Lacand State of Wisconsin, have invented a new and useful Improvementin Axle- Gauge; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification. l

This invention relates toa new and useful Improvenient in apparatus for obtaining the true bevel or inclination t'orthe arms of theaxles of wheeled vehicles, and consists in the arrangement hereinafter described.

In the accompanying drawing- Figure .1 represents the apparatus employed and the mode of transferring the bevel to the gauge.

Figure 2 is an edge view of the bevel.'

Figure 3 isan edge view of the gauge.

Similar letters ot' reference indicate corresponding parts.

In constructing wagons and other wheeled vehicles, it isdesirable to have some special device fox-'determining the bevel or inclination necessary to give the arms of the axles, in order, when insertedin the hubs, that the inner face of the spokes, when immediately below the axle,` should be perpendicularl to the ground line and the center line of said axle; and hence,'iu welding up the axles, the workmen sh'ould have some guide to determine the proper set of the bearings.

The device Ihave invented for this purpose consists of two parts, a bevelend a gauge.

E is the bevel, or that which is applied to the wheel, its tongue, B, which is pivoted to the same, being inserted in the hub, and the arms Gand D adjusted, respectively, in contact with one ofthe spokes and the felly y rlhe arm-D is adjusted in a slot in the bar E, in order to adapt the' instrument to wheels of different r sizes.

-Whcn the bevel is thus adjusted, the tongue B is made fas-t in its angle to the bar E by means ofa setserew. 'Ihe bevel is then removed and placed upon the gauge, as shown in fig. 1.

This gauge consists ot' a central bar with two arms, H, each of' which is provided with short studs or p1ns.

If desired, there may be but. one hinged arm, butin that case the opposite end ot' the gauge-bar must be provided with a stud corresponding in length to those on the arm, and this stud will rest on one arm ot' the axle when the gauge is applied thereto.

The arm H is adjusted to one limb of a square, whose other limb is in contact with the tongue B, as shown in iig. 1, and the arm is secured at the angle thus obtained by means of the setscrew J. glo indicates the true bevel or inclination to be given to the arms ofthe axle. The bevel is always applied to the under side of the axle, and the two preferably correspond in length. p

When thus applied, the stud nearest the joint of the arm`H is placed against the collar ot' the axle-4 arm; or, if the gauge be too short, the next stud may be thus placed. 'The main convenience in providing the gauge with two arms arises from the occasional necessityof setting the arms ot' an axle at different inclinations.

Having thus described my invention',

I claim as new and desire to secure by Letters Patent- The device herein described, consisting of the bar E provided with the tongue and arms O D, and the gauge-bar G, having jointed ends H I, provided with pins o, all constructed and arranged as and for the purpose specified.

ROLLIN C. KELLY.
